Cold Storage

MIT labs win top recognition for sustainable practices in cold storage management.

I2SL Freezer Challenge

Whitehead Institute and MIT named 2020 Organizational Winners in the fourth annual International Institute for Sustainable Laboratories International Laboratory Freezer Challenge. Read the MIT News article.

One ultra-low temperature (ULT) freezer can consume as much energy as a single-family home every day (25 kWh/day). Good management practices on cold storage can significantly reduce energy consumption.

  • Set the ultra-low temperature (ULT) freezers to -70°C instead of -80°C can use up to 40% less energy. “-70 is the new -80″ and samples can be safely stored at this temperature.
  • Keep inventory of samples
  • Clean out freezers to save space and time spent looking for samples
  • Routinely remove ice buildup from -80 freezers
  • Defrost -20 freezers.
  • Share freezer space with other labs instead of buying new ones
  • Replace old, inefficient units with new energy efficient ones

Incentive Program

Eversource provides an incentive when you are buying or replacing existing freezers with any Energy Star certified lab cold storage including refrigeration and freezers. Usually, the incentives are applied directly off vendor’s quote for qualified products. Check with the vendors or EHS to find out how to apply for the incentives.

Freezer Challenge

The International Freezer Challenge, which is run by My Green Labs and International Institute for Sustainable Laboratories (I2SL), is aimed at promoting efficient, effective sample storage for laboratories around the world, and using a spirit of friendly competition to increase sample accessibility, sample integrity, reduced costs, and energy efficiency.

Over a five-month period, challenge contestants implement optimal cold storage management practices, such as defrosting and removing dust from freezer intake or coils, regular cleanouts, organization of inventory on file, and high-density storage. Winners are then chosen based on the amount of energy saved. Additionally, in the spirit of friendly competition and collaboration that pervades the challenge, contestants can earn points for sharing tips about their own cold storage best practices.
